Viscosity Standards for Cone/Plate, Stormer Rotothinner and all other Viscometers

The Quality Control Laboratory has developed with Cannon Instruments a unique listing of Calibration Standards. These standards are calibrated over 6 temperatures from 20 degrees Centigrade to 27.0 Centigrade. These oils are now packaged so they can be used for any Viscometer.

The following table related to a direct comparison to calibration oils supplied by The Paint Research Association( PRA ).

Note:P.R.A. calibration oils are accurate to no better then plus or minus 1% at best. The following oils have an accuracy of +/- 0.2%.

Viscosity standards are based on the National bureau of Standards value of 1.002 centipoise for water at 20 degrees Centigrade. All Standards are traceable to the National Bureau of Standards ( NBS ) / National Institute of Standards and Technology ( NIST ).
